Product Introduction

DAC39720037 is a double row angular contact ball hub bearing that integrates an outer ring and two separable inner rings. It is typically sealed (optional ZZ metal baffle or 2RS rubber seal), filled with grease, and can withstand radial and axial loads generated during vehicle operation. Using high carbon chromium steel (such as GCr15 material), it has excellent characteristics such as wear resistance, low friction, and high service life.

function and application

Load and steering support

This bearing is used in the front/rear wheel hub to support the vehicle's own weight and withstand the radial and axial loads generated during the steering process, ensuring smooth rotation and precise guidance of the wheels

Noise reduction and stability improvement

Advanced sealing design and high-quality lubricating grease reduce friction and vibration, while balancing low noise and long lifespan, enhancing driving comfort.

OEM strict standards

Commonly used for Opel, Ford, Mazda, Changan, Suzuki Swift and other vehicle models

Application diversity

In addition to sedans, it is also suitable for light trucks, agricultural machinery, engineering machinery and other fields

DAC39720037 is a mature and reliable double row angular contact ball wheel hub bearing, made of high-strength chromium steel, equipped with seals and lubricating grease, with high load and high speed performance. Widely used in various vehicle models and non highway machinery fields, it has the advantages of easy installation, low noise, and long service life. Multiple OEM/Aftermarket brands in the market (such as KOYO/NSK, Autorround, TIK, Haina, etc.) offer alternative solutions with high cost-effectiveness, making it an ideal choice for wheel hub bearing replacement and upgrade.
